La Psychologie des Idees-Forces: Tome Premier et Tome Second

Complete in two volumes. xl, 365; 415 pp. 8vo. Maroon leather spines, gilt titles, decoratively stamped paper over boards. The French philosopher explores the idea of the human mind as efficient cause, and the antimony of freedom, continuing the work he began in L'Evolutionnisme des idees-forces (1890), and would continue with La Morale des idees-forces (1907). Fouillee's work overall was an attempt to reconcile metaphysical idealism with scientific advancement.
